I'm Canadian and I've lived in France and the accent in French is different in both countries (as I'm sure it is in other places too). I try not o stress too much about which accent I'm speaking in as a second language. I just get excited if I'm communicating. I'll never forget living in France and hearing people coming towards me speaking a totally unintelligible language, then realizing after they had passed that it was Cockney English (a certain accent from London for you non-native speakers).
